Viscosity is the internal resistance of the fluid layers against flow . Viscosity of a fluid is inversely proportional to the fluidity.
Ideal Fluids:
The Fluids which has no resistance in between their molecules, particles or layers are known as ideal fluids.
The Fluids having zero viscosity are known as ideal fluids.
Real Fluids:
The Fluids which have some resistance in between their molecules, particles or layers are known as real fluids.
The fluids which have some viscosity are known as real fluids.
Nice…
gud answer
That’s really good.
